R. C. MOORE DOUBLE ACTING CHURN Filed May 14. 1955 2 Sheets-Sheet 2 Patented Nov.'19, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to an improved butter churn and more particularly to a novel and improved structure of a so-called duplex or dual type wherein substantially duplicate cream charged containers are mounted in a suitable rotary carrier in such a manner to counteract one another so as to oppose each other with equal force to provide a desired counterbalancing action.

It has been discovered that by coordinating a pair of simultaneously rotatable frames in such a manner as to provide holders for the churning containers and by counterpoising the containers to assume positions at right angles to each other and filling said containers with equal amounts of cream they coact in unison when set in rotation to work in opposition and when associated with a suitable source of power and a support provide for uniform continuity of rotation to equalize stress and strain and to minimize the power required to operate such improved double-acting churn structure.

The foregoing comprehends in a general structural way the developments to be hereinafter described, though it may be introduced here that other features and advantages, especially of a specifically structural nature, will become more readily apparent from the complemental illustrative drawings and the explanatory descriptive matter.

In the drawings:

Figure 1 is an elevational view of the complete machine or structure developed in accordance with the principles of the present inventive conception.

Figure 2 is an end view, that is a view looking at Figure 1 in a direction from left to right.

Referring now to the drawings by distinguishing reference numerals it will be observed that 3 denotes the base. This comprises a pair of suit able risers or rests 4 with a board superimposed thereon to serve as a platform 5 for the electric motor. Incidentally this motor 6 constitutes the preferred source of power but it is evident that the machine may be either hand operated or controlled by an engine or any appropriate prime mover. The motor is here shown as having its shaft equipped with a pulley I to drive a belt 8 trained over a larger pulley 9 on a shaft carrying a pinion Ill. The shaft I0 is supported on an upright or standard I I whose upper end is apertured to provide a suitable bearing. There is a complemental upright l2 on the opposite side of the structure which has its upper end apertured to provide a similar bearing. The numeral I3 desig- (Cl. 259-57) I nates a horizontal brace rod extending through the intermediate portions of the uprights and 14 represents a V-shaped brace whose crotch portion is fastened as at 15 to the intermediate part of the board or platform 5, the arms being fastened as at IE to the end portions of the brace rod [3. This provides for rigidity and stability in the frame structure which constitutes the support for the double-acting rotary carrier. This rotary carrier is made up of a pair of substantially rec- 10 tangular companion frames l1 and I8 fastened together in positions at right angles to each other and provided with suitable trunnions I9 and mounted for rotation in the bearings in the upper ends of the uprights. The trunnion i9 is pro- 15 vided with a relatively large power take-off gear 2| which is in mesh with the pinion I0 whereby to rotate the two frames l1 and I8 in unison. These frames obviously serve as holders for the jars or other containers 22 for the cream to be 20 churned. Inasmuch as each frame structure is the same in construction I will describe but one.

It may be said that one end bar 23 of the frame is provided with right angularly disposed arms 24 having upturned ends 25. These features serve 25 to accommodate the cruciform rests for the bottoms of the jars. Each cruciform rest comprises the members 26 and 21 cooperating with the features 23 and 24. As a general proposition the frame is made of metal and the cruciform rests or adapters are wood to provide the desired cushioning properties for the bottom of the jars 22. The opposed end bar 28 of the frame is provided with a thumb screw 29 carrying a lid 30 to serve as an effective cover for the neck of the jar. The numeral 3| is merely a pet cook or vent to relieve gas pressure which is sometimes built up in the jar during the churning operation.

Importance is attached to the-arm formation at one end of the frame which serves to accommodate the cushioning cruciform adapters which function as rests to accommodate the glass jars. The clamping lid and retaining means at the opposite end of the frame also possess their proportionate share of merit. It follows, therefore, that these features, particularly the rotary frame unit as a carrier for the jars, have been carefully selected and mechanically coordinated to promote smooth and dependable operation due to the compensating and counterbalancing factors, whereby to render the structure devoid of jerky operation with the result that proportionately less power is needed. for effective control and well-balanced operation.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having thus described the invention, what is claimed as new is: r

As a component part of a structural assemblage of the class described, a rotary counter-balanced carrier unit for a churning vessel including a substantially rectangular frame, a. closing lid attached by an adjusting screw to one end member of the frame, the opposite end member being provided with centrally disposed outstanding arms, and a cruciform adapter device attached to said last named end of the frame and associated with said arms.
